Tip & How-To about Pontiac Grand Prix

Saving Your Tires

The largest vehicle expense short of a catastrophic mechanical failure can be the purchase of tires. After spending anywhere from a few hundred dollars to upwards in the thousands for tires why not protect your investment? Many tire stores offer packages for road hazard situations which usually covers tire repairs and lifetime rotate and balance as well as proration of the tire if tire becomes unrepairable.Ask your tire dealer what their road hazard packages cover? Some tire dealers even offer lifetime alignment or extended alignment service packages.

One of the most common cause for tire failure is improper inflation.Underinflated tires can cause excessive flexing of the sidewall causing the rolling resistance to increase (friction) and can not dissipate heat the way it was intended.This can lead to blow outs or tread separations.Overinflated tires can wear out the center tread and allow to much pressure to build up and cause a tire to blow out. Most vehicles have a placard in a door jam or glove
box that states what manufacturer suggests what the air pressure should be set to.If unable to locate the placard the owners manual contains the same information.This is what the air pressure should be set to.Tires have a maximum pressure printed on the sidewall this is more to advise what the tire can handle not a guideline for inflation.

A long term sign of an under inflated tire is inner and outer edge wear this causes the tire to not roll evenly across the road surface and puts the vehicles weight on the edges of the tire. An overinflated tire will
cause the the center tread of the tire to wear out.

You purchased a tire rated for 60000 miles and it only lasted for 30000? The reason for this is usually due to lack of tire rotation so the drive tires end up wearing out faster then the non drive tires. Proper tire
maintenance is the key to longevity of your tires.Most importantly proper tire pressure.Most manufacturers recommend tire rotations between 5000-7500 following this will maximize the life of your tires.Tire rotation
procedure can vary from a front wheel drive (FWD), rear wheel drive (RWD),all wheel drive (AWD), or four drive (4WD) your owners manual should tell you the best way to have your tire rotated for your vehicle. At one time it was suggested to never cross rotate tires due to damage occurring this is no longer the case. Advancements in tire technology has changed this so cross rotating is now a regular practice. There are some exceptions such as performance rated directional tires designed to only be mounted one way on the vehicle left or right side these can
only be rotated front to back.Some vehicle are now stock with different size front and rear tires so rotating
really is not an option.

After your tire replacement or rotation an alignment is a large a key to tire longevity and avoiding premature tire wear. In a perfect world there are no pot holes in the roads or curbs to hit but we all know that is not reality.These things can easily cause one of the alignment angles to go out of specification drastically reducing tire life. I mentioned earlier that some shops offer a lifetime or an extended alignment service plan this
is definitely a great option depending on what your intentions with the vehicle are.This can save you you a lot of money in the long run.About once a year or every 12000 miles you should have the alignment checked and set if needed even sooner if you commonly are hitting potholes and curbs.

Following these simple rules will allow you to get the maximum mileage from your tires.

91 accord lx front wheels srem to wobble when hitting bumps in thr road


A loose front end is no joke. Ignoring the problem can cause premature / uneven tire wear and other costly repairs or accident due to catastrophic failure when least expected.

Typically, front end pivoting points used for steering - called "ball joints" - wear out providing similar sensations as you describe. This is not really a DIY type of repair - and should be brought to a trusted mechanic for a proper diagnosis and repair.

how to remove rear end gears


I doubt even fords service manuals will help

I spend hundreds of dollars for all the manuals
for all my vehicles, but that doesn't make you a mechanic

You need lots of expensive tools & knowledge

I don't know the question

Your removing the rear axle hubs to do the bearings,
or pulling the rear drive axles, to do the center differential

1998 chevrolet suburban flashing check engine light


First thing to do when check engine light comes on are the most basic but most important. Shut off vehicle and check engine oil level, then wait till vehicle cools down and check coolant level (be careful) if these 2 things are ok then the vehicle is in no danger of catastrophic failure... It could be something as simple as an 0 2 sensor. Usually your local car box store( in Canada it's Canadian Tire) will have theOBD controllers on sale for around a hundred bucks, that's usually what a garage will charge you to read the code, and check it yourself. All codes are available on line then you at least you know what your dealing with. Also check your brake fluid!

Warning stating reduce engine power and something about stability


Reduced power mode is when the electronic ignition is strategically is not firing all the cylinders to prevent catastrophic failure of your engine. The reason for the GM Engineers put the reduced power mode in the vehicle is so you can drive the vehicle under 50Mph for about 50 miles to a mechanic before the vehicle completely dies.
